factors affecting enzymes

• what factors affect enzyme activity

  • temperature
  • ph level
• what does optimum mean in terms in terms of temperature

  • the temp where enzyme activity is the highest
• what is ph

  • a measure of acidity
• what does an extremely high ph do to enzymes

  • causes them to denature
• what does denature mean

  • the change of an enzymes active site which prevents it binding to its substrate
• what happens to the rate of activity if substrate concentration increases

  • the rate of reaction increases up to a point because an increase in substrate concentration means more enzyme-substrate complexes can be formed
• why does the rate of reaction become unaffected even if substrate concentration increases

  • because it reaches the saturation point
